 Traditional Voice-over-IP applications such as Microsoft NetMeeting 
 assume that the user is on a machine with a fixed IP address. If, 
 however, the user connects to the Internet, via a wireless network, 
 on a handheld device, his IP address frequently changes as he moves 
 from one subnet to another. In such a situation, we need a service 
 that can be queried for the most current IP address of a person whom 
 we wish to contact. In this project, we design and implement such a 
 directory service. The service authenticates all callers and callees, 
 is robust against most host failure, and scales to several thousand 
 registered users.
